Woodpeckers use their long beaks to dig for and eat insects living in 4 points tree trunks. A new species of woodpecker with a very long beak evolves.
Which statement best explains how the environment influenced the
development of this new species?
1. A harmful mutation occurred in the gene for beak length.
2.The insect population increased, the birds that ate more insects grew longer beaks.
3. Insects that live deep in tree trunks spread to trees in the woodpeckers' territory.
4.The long beak is an adaptation to help woodpeckers fight off predators

six grader is what i am ssorry

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

i dont know it at allnow im just getting points at this pint

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
